"A spy, we think," said Alfred.
"Do you mean he has been here?" said the officer in an incredulous tone.
"Yes; not more than a half hour ago," answered Alfred, "and he is here somewhere on the grounds; we are trying to find him."
"One moment; there is a call on the 'phone; excuse me," said the lieutenant, as he disappeared into the next room.
"Yes, he is here!" Alfred heard the lieutenant say. "Do you want him?"
Alfred was moving toward the door when the lieutenant appeared and announced: "They have arrested a peddler at the gate. The colonel wishes to speak to you."
Alfred took the receiver. "They have the peddler at the gate. They are bringing him over now, so be kind enough to get here at once," was the message.
Alfred hurried to the commandant's office, and met Ralph at the door.
"Too bad; they have gotten the wrong peddler. He is in that room. Look in through the door and see what you think," said Ralph.
